Abstract：

Qinghai Province is located in the alpine region, and its ecosystem is very fragile. The Ecological Vulnerability Classification 1-km Raster Dataset in Qinghai Province of China (2015) was developed based on the data in 2015 and the "SPR" (sensitivity-pressure-resilience) model and stochastic forest model. The data items include slope, elevation, topographic relief, soil erosion sensitivity, land degradation sensitivity, NDVI, average annual temperature, average annual precipitation, population density, etc. Five groups of vulnerability were identified, they were slight, mild, moderate, severe, and extreme. The spatial resolution is 1 km. The dataset is archived in .tif format; it consists of five data files with data size of 1.30 MB (Compressed into one file with 165 KB). The analysis paper was published at the Journal of Qinghai Environment, Vol. 30, No. 4, 2020.
